Before you decide in Letchworth Garden City
Replacing a bungalow in SG6 with two or more homes needs planning permission for the new homes, and North Hertfordshire District Council will look closely at the number of homes, their height, parking, bins and garden space for each household.
A replacement can sometimes fit better than squeezing a new home behind a bungalow that stays, because the whole plot can be laid out from scratch. Neighbours are consulted either way, and a design that respects single-storey homes next door usually meets fewer objections.
The next steps, locally
Once you’ve chosen a route, we prepare the planning case for North Hertfordshire District Council, usually starting with pre-application advice. Neighbours are consulted when the application goes in, we answer any queries from the planning officer, and the council decides. If you’re selling, your solicitor handles the transfer; if we’re building, you receive a written quote after design and survey, before any construction is agreed.
Free plot appraisal
We look at the plot’s width and depth, the access, the planning history nearby and the character of the street, then talk through what you want. It’s free, with no obligation, and a site visit follows if it looks viable.
Compare the options
We sketch what could realistically fit: a home behind, a home beside, or a replacement scheme. You see the trade-offs for each, including what happens to your own garden and parking, before choosing a route.
Choose your route
You can sell a plot and stay put, sell subject to planning, grant an option, enter a joint venture, or keep the land and have us design, get planning for and build a new home on it.
Planning application
We prepare drawings and reports designed around single-storey neighbours and the street scene, usually seek pre-application advice, and submit. The council consults neighbours and makes the decision.
Worth checking early
- You’ll keep a smaller garden, and a drive alongside your bungalow brings cars past your windows.
- A two-storey home on a road of bungalows is often resisted, so designs may need to stay low.
- Filling the gap beside a bungalow can change the look of the street, which councils weigh carefully.
Letchworth Garden City: questions to ask
Is it worth replacing my bungalow in Letchworth Garden City with more homes?
Sometimes, where the plot is large and the bungalow is dated or poorly placed. Replacement can fit more homes than building behind, but you would need to move out during the work. We compare both approaches for your plot during the appraisal.
How much garden does a bungalow in Letchworth Garden City need to keep?
There’s no single figure. Councils look for enough private garden for both the existing home and the new one, and many have guidance on minimum garden sizes. We check your council’s guidance during the appraisal.
Could I build a home for a relative on my bungalow plot in Letchworth Garden City?
Yes, through our design and build route. You keep the land, and we design, get planning for and build the new home. A separate home needs planning permission; an annexe used as part of the main house is treated differently.
Do I need to sell my Letchworth Garden City bungalow to develop the plot?
No. You can keep the bungalow and sell a plot, have us build on the land for you, or enter a joint venture. Replacing the bungalow is only one of several options, and staying put is often simpler.
